The manufacturing process of tungsten steel saw blades can be divided into the following steps:
- Ingredients: According to the performance requirements and uses of the tungsten steel saw blade, select appropriate tungsten steel powder and cobalt powder, as well as an appropriate amount of additives, binders and other raw materials, mix them together and stir thoroughly.
- Forming: Put the mixed raw materials into the mold and press and form under a certain pressure and temperature. The formed blank needs to be trimmed and polished to remove defects such as burrs and flash.
- Sintering: Put the shaped body into a sintering furnace for sintering. During the sintering process, the binder in the raw material will evaporate and form pores, while the tungsten steel powder and cobalt powder will undergo physical and chemical changes to form a tungsten steel sawtooth blade material with specific properties.
- Grinding: The sintered tungsten steel saw blade needs to be ground to remove the oxide layer and pores on the surface and make the surface flatter and smoother. At the same time, the geometric shape and dimensional accuracy of the tungsten steel saw blade can also be adjusted through grinding.
- Coating treatment: In order to improve the hardness and wear resistance of tungsten steel saw blades, coating treatment can be carried out. Commonly used coating materials include titanium nitride, titanium carbonitride, titanium aluminum nitride, etc. Coating treatment can significantly improve the performance and service life of tungsten steel saw blades.
- Inspection and packaging: The manufactured tungsten steel saw blades need to undergo quality inspection to ensure that they meet the specifications. Qualified products need to be packaged to protect them from damage or contamination.
It should be noted that the manufacturing process of tungsten steel saw blades involves multiple complex physical and chemical changes and process processing links, which requires high manufacturing equipment and process technology. Therefore, the cost of manufacturing tungsten steel saw blades is relatively high, and corresponding manufacturing equipment and process technology foundation are required.
